近年来由于气候变化、极端天气现象及其相应的自然灾害的频繁发生,致使人类面临严峻的挑战。全球环境变化问题已倍受瞩目。值得注意的是,湿地碳循环在气候变化中具有不可忽视的作用。大气中CO_2含量至少在40万年时间里一直比较稳定,保持着280ppm的水平。可是工业时代开始以后,这个数字已经跳到了360ppm,而且还在继续升高。尽管人类对全球变暖的原因争论较多,但多数学者认为人类活动的因素不容忽视。德国马普学会的科学家莫伊普·拉提夫最近的研究表明,导致这一结果本要是由于人类在其
In recent years, mankind is facing severe challenges due to the frequent occurrence of climate change, extreme weather phenomena and the corresponding natural disasters. The issue of global environmental change has drawn much attention. It is noteworthy that the wetland carbon cycle has a significant role to play in climate change. Atmospheric CO 2 content has been at least 400,000 years of time has been relatively stable, maintaining the level of 280ppm. But after the beginning of the industrial age, this figure has jumped to 360ppm, and continues to rise. Although human beings are more controversial about the causes of global warming, most scholars think that the factors of human activities can not be ignored. Recent research by Moeppe Latif, a scientist at the German Maple Institute, has shown that the results that led to this result were due to the fact that humans
